300 is a highly successful 2007 historical fantasy film adapted from the graphic novel 300 by Frank Miller. Although the novel is riddled with cultural and historical errors, it loosely depicts the heroic stand by the Spartans at the Battle of Thermopylae and the events leading up to it from the perspective of Leonidas I, King of Sparta. The film is directed by Zack Snyder with Frank Miller attached as an executive producer and consultant, and was shot mostly with bluescreen to mimic the imagery of the original comic book.
